By default, a vmware-services-eam.conf rsyslog configuration file includes the service logs when syslog is configured on vCenter, but it must be verified.

At the command prompt, run the following command:

# cat /etc/vmware-syslog/vmware-services-eam.conf

Expected result:

#eam.log
input(type="imfile"
File="/var/log/vmware/eam/eam.log"
